It is super easy to make yogurt using our Bacillus Bulgaricus yogurt starter culture.

All you need is a pack of Bacillus Bulgaricus starter and milk. You can use a yogurt maker of course but it is absolutely not required.

Here is how to make yogurt using just items you find at home.

First, find some containers to make the yogurt in. Mason jars work best, however any type of container you are comfortable with will work just as well.

The instructions below are for 1 liter (a quart) of milk so you need to make more or less than that, adjust them accordingly.

Ingredients

1 liter (a quart) of milk
1 gram (just over 1/4 teaspoon) of Bacillus Bulgaricus yogurt starter

Preparation

Bring the milk to a gentle boil. The milk should boil in order to kill any existing bacteria in it, which could react with the Lactobacillus Bulgaricus. Milk boils at about 212°F / 100°C. Be careful not to burn it, otherwise your yogurt will inherit the burnt taste.
Cool the milk down to 110°F / 43°C. The easiest way to test for the right temperature is to dip your pinky finger in the milk – if you can comfortably count to 5 then the milk is just right.
Move the milk to a separate processing container. You can use multiple smaller containers too.
Add 1/4 teaspoon of the starter. Mix well. This is important! Stir for a good 3-4 minutes (do not use a mixer, stir by hand). If you used more than one container, distribute the pack’s contents evenly in respect to their volumes.
Cover the container loosely with a lid. Do not close it air-tight.
Wrap the container well in blankets or cover with a tea cozy and let it sleep. Keep out of any draft.

The fresh yogurt will set in about 5-6 hours. If the place is cold the process may take longer (10-12 hours). You can easily check if the yogurt has set by tipping the container a bit — its contents will be firm instead of liquid. For a denser yogurt with more acidic and tart taste you can leave it culturing longer (e.g. overnight).
